DESCRIPTION
DESCRIPTION
The 2.4 Liter (146 cu. in.) in-line four cylinder engine is a single over head camshaft with mechanical lash
adjusters and four valves per cylinder design. This engine is NOT free-wheeling; meaning that the pistons will
contact the valves in the event of a timing chain failure.
The cylinders are numbered from front of the engine to the rear. The firing order is 1-3-4-2.

date information.
DIAGNOSIS AND TESTING
ENGINE DIAGNOSIS - INTRODUCTION
Engine diagnosis is helpful in determining the causes of malfunctions not detected and remedied by routine
maintenance.
These malfunctions may be classified as either performance (e.g. engine idles rough and stalls) or mechanical
(e.g. a strange noise).
Refer to PERFORMANCE DIAGNOSTIC TABLE and ENGINE MECHANICAL DIAGNOSTIC

  • Page 137 Fig. 158: Solenoid Valve, Hydraulic Brake Pumping Element/Hydraulic Lash Adjusters, Upper Pumping Element & Oil Accumulator Courtesy of CHRYSLER GROUP, LLC Variable valve actuation controls the operation of the intake valves.

  • Page 139 The five phases are: Fig. 160: Full Lift Courtesy of CHRYSLER GROUP, LLC Full Lift. When variable valve actuation functions in the full lift phase, all of the camshaft lobe lift is transferred to the intake valves. The intake camshaft lobe is designed with a very aggressive lift and duration profile.
  • Page 140 2014 ENGINE 2.4L - Service Information - Dart Fig. 161: Early Intake Valve Closing (EVIC) Courtesy of CHRYSLER GROUP, LLC Early intake valve closing (EVIC). When variable valve actuation functions in the EVIC phase, the camshaft lobe lift is transferred to the intake valves at the beginning of the lift duration cycle. However, the hydraulic connection between the camshaft lobe and the valves is taken away before the lobe reaches full lift.
  • Page 141 Fig. 163: Multi-Lift Courtesy of CHRYSLER GROUP, LLC Multi-Lift. Multi-Lift is a combination of EVIC and LIVO because the hydraulic connection between the camshaft lobe and the intake valves is closed early and then re-opened later in the cycle. This creates a longer duration valve lift with a smaller amount of lift.
